Radiography is a Non Destructive Testing carried out using X-ray generators or artificial gamma sources. X-rays or gamma rays pass through the object to be radiographed and record an image on a radiographic film, placed on the opposite side. The quality and amount of radiation reaching the film will be largely determined by the objects thickness and density, e.g. a crack in a weld will increase the amount of radiation falling on the film in that area due to a reduction in thickness. When the film is processed a negative is produced. The thin areas of an object will be darker than the thicker areas, therefore most weld defects will show up dark in relation to the surrounding areas. Radiography Course contains the Basic Radiation Safety (BRS), the Radiographic Interpretation (RI) and Radiographic Testing (RT). Radiography can be used for inspection of welds, castings and wrought materials, in metallic and non metallic materials.
